ENVELOP.

Specification of Letters Patent.

Patented July 19, 11.921.

Application filed May 22, 1919. Serial No. 298,998.

To all whom it may concern:

Be it known that I, Jnnno'm) P. DE VAUGHN, a citizen of the UnitedStates, and a resident of Buffalo, in the county of Erie and State ofNew York, have invented a new and Improved Envelop, of which thefollowing is a full, clear, and exact description.

This invention relates to envelops, and has reference more particularlyto an envelop used in mailing correspondence. and for other purposes,and comprising a body having overlapped flaps, and a closing flapadapted to be inserted underneath the overlapped flaps, the closing flappresenting a surface for an address or other inscription, thearrangement being such that the address is visible when the closing flapis in position under the other flaps. The invention also relates to anenvelop having flaps overlapped and secured together, and a closing flapadapted to bear an inscription and to be inserted under the first flaps,which are provided with an opening to render the inscription visiblewhen the envelop is closed.

The object of the invention is to provide a simple and durable envelopwhich can be inexpensively produced, which is capable of repeated useuntil worn out, and upon which the address or other inscription can bereadi] y produced by means of a typewriting machine or otherwise.

A further object of the invention is to provide an envelop easilymanipulated in opening and closing the same, in which the contents aresecurely held although the envelop is not sealed, and which may have twoaddresses or other inscriptions permanently applied thereto although oneonly at a time is visible when the envelop is in use.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a planview of the blank from which the envelop is formed;

Fig. 2 is a plan view of the blank, showing the end flaps folded intoposition and secured together;

Fig. 3 is a transverse section on the line 3-3 of Fig. 2;

Fig. 4 is a plan view of the completed and closed envelop ready for use;and

Fig. 5 is a transverse section on the line 5--5 of Fig. 4.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that the envelop can be manufactured in theusual manner, from paper or other material adapted for the purpose, andin various shapes and sizes. While it is capable of general and ordinaryuse it is of particular value in the offices of railroads or similarindustries in which large quantities of envelops of all sizes and kindsare used, such use in many instances aggregating millions annually. Itis designed primarily for so-called shuttle use. That is, for sendingback and forth between two specific oflices or destinations, betweenwhich there is a continuous inter change of mail or other corresiiondence. This envelop can be used for such purposes repeatedly untilit is worn out. It bears, permanently inscribed thereon, both addresses,one or the other of which is positioned to be visible according to theintended destination in question.

My envelop serve to replace those at pres ent in use, bearing certainaddresses printed or otherwise permanently inscribed thereon, which,after having been used once must be re-distributed empty before they canbe used again. In this way a great saving is effected.

Referring more )articularly to the drawings, the envelop comprises abody section 10, having at each extremity a tapered end flap 1.1,terminating in an extension 12 havingparallel sides. One of theextensions 12 is provided with a gurnmed surface 13. Each. extension hasformed therein an elongated opening 14 having rounded ends. Theseopenings are similarly located and proportioned.

At the opposite, longitudinal edges of the body 10 are formed similarclosing flaps 15, preferably tapered as 'is shown in Figs. 1 and 2.

In forming the envelop, the end flaps are folded inwardly and overlap.They are permanently secured together by means of the gummed surface ofthe one extension 12. The openings 1-l register as is shown in Fig. 2.The envelop is now ready for-use. Each of the closing flaps hasdelimited thereon an address space 16, preferably similar in form to theopening 1 1. The closing flaps are folded inwardly and inserted underthe end flaps. When so positioned, the address spaces 16 Will registerwith the openings 14. The address 17, or other inscription is producedupon each closing flap, and this inscription will be visible through theopen ings 14, according as the closing flap iunder or overlies the otherclosing flap.

In providing two permanent addresses in this way, the envelop can beused repeatedly in sending matter bank and forth between twodestinations. In each case the proper and requisite closing flap iscaused to overlie the other closing flap and conceal the address uponthe latter.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. An envelop comprising a body having overlappedflaps having registering openings when so overlapped, and a closing flapattached to said body and adapted to be insertedunderneath said firstflaps, said closing flap presenting a surface for an address, saidfirst-mentioned flaps being arranged to render said address-surface ofsaid closing flap visible when said closing flap is in positionunderneath said registering openings.

2. An envelop comprising a body, end flaps attached thereto and inwardlyfolded and overlapped, the overlapping portions of said flaps beingpermanently secured together and having an opening through theoverlapped portions, and closing flaps attached to said body, atopposite sides thereof, said closing flaps being adapted to be 'loldedand inserted under said end llaps and to bear an address visible throughsaid open ing.

3. An envelop comprising a body, tapered end flaps attached thereto andinwardly folded and overlapped, the overlapped portions of said flapsbeing senured together permanently, and having registering openingstherethrough, and closing (laps a l'ta 'hed to said body at oppositesides thereof, l\otween said end flaps, said closing flaps being adaptedto be folded and inserted under said end flaps, and each. bearing a llll'lllllllvllll address-inseription, said address-inst'ription of theuppermost closing flap being visible through said openings.

4:. An envelop of the character spwilied, and comprising a body havingend llaps overlapped and permanently secured together, said end flapshaying elongated registering openings in their overlap nal portiod-a.and closing flaps at the upper and lower ends of the body a l:1 ted tobe inserieil beneath said end flaps and overlapped and to over orunderlie each other when so inserted, said closing flaps having(:(n'rosponding areas adapted for permanent insertion thereon oipermanent addresses, emh oi said areas adapted to be visible through theaforesaid registering OIKIllHgS, according as one closing Hap under oroverlies the other closing flap.
